How do i validate ampersands with VBSEO

Trying to check my markup validation,

Code:

Line 354,         Column 514:     reference to entity "fs" for which no system identifier could be generated     
…www.youtube.com/v/GpcJNEWKzCY&hl=en&fs=1&"></param><param name="allowFullScree…                ✉     
                  This is usually a cascading error caused by a an undefined entity       reference or use of an unencoded ampersand (&) in an URL or body       text. See the previous message for further details.

This is only showing in the CSM here http://www.devils-shadow.com/, it does not happen in the forums

Had a search and only found How to validate with vBseo Virtual HTML? as a solution but i checked my functions_vbseo_seo.php file and it was already what the post was telling me to change it to

& should be written as & in all urls. Your error is NOT in virtual html. It's coming from your sidebar video blocks. Just edit the urls to be & in the editor, or even delete the params of the youtube movies, as all you need is the video 'v' id to have it play.
